  1. First find the square of the velocity (there's a formula for that), then find the work done which will lead you to the force. range x = V²sin(2Θ) / g 60.0 m = V² * sin90º / 9.8m/s² V² = 588 m²/s² Then the QB gave...

  3. Doug can catch the ball while it is rising, or at its maximum height or while it is falling depending on the initial velocity.But since douglas is at the tight end he should catch the ball while it is rising. Here we need to know the...

  5. Use the trajectory eqn: y = h + x·tanΘ - g·x² / (2v²·cos²Θ) 2m = 1.8m + xtan35º - 9.8m/s² * x² / (2(12m/s)² * cos²35º) 0 = -0.2 + 0.7x - 0.0507x² quadratic in x, solutions at x = 0.29...

  6. There is a simple formula for this: range x = V²sin(2Θ) / g Here, 177 m = V² * sin67.2º / 9.8m/s² which solves to V = 43.4 m/s Seems super-exceptional to me. (That's almost two football fields, btw...
